Samsung has pulled the wraps off a game-changing innovation in electric vehicle (EV) battery technology. Introducing their cutting-edge solid-state batteries, the tech giant has unleashed a power source that promises to rewrite the rules of EV performance and practicality.
At the SNE Battery Day 2024 expo in Seoul, South Korea, Samsung revealed that its pilot solid-state EV battery production line is now fully operational. “We built a pilot line last year to mass-produce all-solid-state batteries by 2027,” said Samsung SDI.
The battery’s initial batches have already been delivered to EV manufacturers for evaluation. “We supplied samples to customers from the end of last year to the beginning of this year and are receiving positive feedback,” Samsung SDI stated.
Potential benefits of solid-state batteries
These solid-state batteries hold the promise of revolutionizing the electric vehicle (EV) industry, as they are expected to be smaller, lighter, and safer than the lithium-ion batteries currently used in most EVs. They have the potential to power electric vehicles with a 600-mile range, charge in just 9 minutes, and have a lifespan of 20 years.
Impressive energy density
Samsung’s oxide solid-state battery technology boasts an impressive energy density of 500 Wh/kg, nearly double the 270 Wh/kg density of mainstream EV batteries. This increased density could potentially double the driving range of current electric vehicles.
Initial target market and affordable alternatives
However, due to their high production costs, these batteries’ initial application will be limited to the “super premium” EV segment, which typically offers a driving range of around 600 miles per charge. In addition, Samsung will be introducing high-nickel NCS products for the premium segment.
Alongside its work on solid-state batteries, Samsung is also developing more affordable lithium iron phosphate (LFP) and cobalt-free batteries, as well as a dry electrode production method to reduce costs. “We will not only match the price in the popular and entry-level segments, but also mass produce products that can be rapidly charged in 9 minutes by 2026,” highlighted Samsung SDI.

Competitive landscape, charging infrastructure
While Samsung’s solid-state battery progress is significant, the company must navigate a competitive landscape dominated by Chinese manufacturers. Limited availability of high-speed charging infrastructure remains a notable challenge, as some Chinese battery makers already offer 5C or 6C charging speeds, equivalent to 480kW and even 600kW charging stations.
Broader market trend: “Million-Mile” batteries
However, the visible approach of all battery makers to offer longer lifespans of batteries, often referred to as “million-mile” batteries, is a notable trend. Samsung’s vision to “extend the battery life to 20 years” aligns with this broader market trend.
